NAME 
pmc/luatable.pmc - Lua Table
DESCRIPTION
LuaTable extends LuaBase to provide a class with the behaviour of the Lua Table type.
This implementation is based on the Lua 4.0 one.
Overloaded Methods
void init()- Initializes the instance.
void mark()- Marks the hash as live.
void destroy()- Free hash structure.
STRING *name()- Return the string "table".
PMC *clone()- PMCs are always handled by-reference in Parrot. So, copying register contents only copies the reference to the PMC. For LuaString, LuaNumber, LuaBoolean, this is not correct, as Lua has by-value semantics for these types. In order to be able to handle register "move" instructions, this should be implemented using clone(). However, LuaTable and LuaFunction do have by-reference semantics. As you don't know the type during compile-time of an object, just always use clone() to copy register contents. LuaTable and LuaFunction should therefore only clone the reference to themselves, not make a deep copy.
STRING *get_string()void set_pmc(PMC *other)PMC *get_pmc_keyed (PMC *key)tableaccessor.void set_pmc_keyed(PMC *key, PMC *value)tablemutator.INTVAL elements()- Returns the number of elements in the table.
non-Vtable Methods
INTVAL is_equal(PMC *value)- The
==operation. Compares reference (not in depth). INTVAL cmp(PMC *value)
